Good afternoon, running into something I haven't seen before. Replacing a barrel on a shot out 300Wby back to original 300 H&H and the location of the rear sight boss / bulge in the barrel is different between old barrel and new. They're different by about 190 thousands. Everything else is identical, including overall length. Does anybody know when this change occurred? Or do I just have a one-off mistake barrel? The replacement barrel doesn't fit in the old stock due to the difference in location sadly, so deciding where to go from here...
Thanks!
